2008 GMC Sierra 1500 electrical system problems

On 04.12.2014 after going to the store, parked under the carport. The time was 10pm. While inside heard a pop sound around 10:15 pm. Went outside and the truck was on fire. Put truck in neutral and pushed it from under the carport, trying to save damage to the house. Fire dept came and put the fire out. The fire warped all the vinyl under the carport. Lucky it didn't catch the house on fire. The fire was worse on the passenger side of the vehicle.

Tl* the contact owned a 2008 GMC sierra 1500. While driving 55 MPH, smoke emerged from the vents on the passenger side of the vehicle. The vehicle was pulled over to a shoulder lane where the passenger side began to catch fire. The contact stated that wires were visible prior to the fire. The fire department extinguished the fire. No injuries were sustained. The vehicle was towed to the contact's residence and the insurance company deemed the vehicle destroyed. The cause of the failure was not determined.
